Connections - I/O bus
The right-hand I/O bus is the outgoing I/O bus. The left-hand I/O bus is the incoming I/O
bus. Always connect the right-hand I/O bus to the left-hand I/O bus of the next module.
Points to be considered when connecting the I/O bus
The I/O bus cables are not hot-pluggable. Always disconnect the system power from all
modules when removing or connecting I/O bus cables.
Connect the modules to each other via the I/O bus. Use the supplied I/O bus cables (10 cm) or a long
I/O bus cable (72 cm, article number 5219112). Always take the permitted I/O bus cable length into
account (maximum total length and maximum length between modules).
The controller's I/O bus connector has a dust cover. Remove the dust cover before connecting an
I/O bus cable. No I/O bus cable is connected in the outgoing I/O bus connector of the last module;
always install a dust cover there
